我正在写一个脚本，想在Python 2.6中尝试用很多不同的编码方式来处理字节。有没有办法获取一个可用编码的列表，以便我可以逐个尝试？

我这样做的原因是因为有用户的文本编码不正确，里面有一些奇怪的字符。我知道是哪个Unicode字符导致了这个问题。我想给他们一个答案，比如“你的文本编辑器把这个字符串当成X编码来理解，而不是Y编码”。我打算先用一种编码来编码那个字符，然后再用另一种编码解码，看看能否得到相同的字符序列。

也就是说，类似这样：

for encoding1, encoding2 in itertools.permutation(encodinglist(), 2):
  try:
    unicode_string = my_unicode_character.encode(encoding1).decode(encoding2)
  except:
    pass

错误处理 unicode 字符编码文本编辑器编码转换字节处理编码

也许你可以试试使用这个叫做 Universal Encoding Detector（chardet）的库，而不是自己去实现一个。

>>> import chardet
>>> s = '\xe2\x98\x83' # ☃
>>> chardet.detect(s)
{'confidence': 0.505, 'encoding': 'utf-8'}

这里的其他回答似乎都在说，程序化地构建这个列表很困难，而且容易出错。不过，其实这样做可能没必要，因为文档里已经包含了Python支持的标准编码的完整列表，这一点从Python 2.3开始就有了。

你可以在以下链接找到这些列表（针对每个已经发布的稳定版本）：

下面是每个文档版本的列表。如果你想要向后兼容，而不仅仅是支持某个特定版本的Python，你可以直接从最新的Python版本复制列表，然后检查每个编码在你运行程序的Python中是否存在，再尝试使用它。

如果这些信息对某些人的使用场景有帮助，文档中还列出了一些Python特定的编码，其中许多编码主要是供Python内部使用，或者在某种程度上比较奇怪，比如'undefined'编码，如果你尝试使用它总是会抛出异常。如果你像提问者一样，想弄清楚某些文本在现实中使用了什么编码，可能完全可以忽略这些编码。从Python 3.7开始，列表如下：

["idna",
 "mbcs",
 "oem",
 "palmos",
 "punycode",
 "raw_unicode_escape",
 "rot_13",
 "undefined",
 "unicode_escape",
 "unicode_internal",
 "base64_codec",
 "bz2_codec",
 "hex_codec",
 "quopri_codec",
 "uu_codec",
 "zlib_codec"]

一些旧版本的Python有一个string_escape特殊编码，我没有把它包含在上面的列表中，因为它已经从语言中移除了。

最后，如果你想更新我上面的表格以适应更新的Python版本，这里有一个（粗糙且不太稳健的）脚本，我用它来生成这些表格：

很遗憾，encodings.aliases.aliases.keys() 这个方法并不是一个合适的答案。

aliases（就像你预期的那样）包含了多个不同的键映射到同一个值的情况，比如 1252 和 windows_1252 都映射到 cp1252。如果你用 set(aliases.values())，会节省很多时间，而不是用 aliases.keys()。

但是还有一个更糟糕的问题：aliases 并不包含那些没有别名的编解码器（比如 cp856、cp874、cp875、cp737 和 koi8_u）。

>>> from encodings.aliases import aliases
>>> def find(q):
...     return [(k,v) for k, v in aliases.items() if q in k or q in v]
...
>>> find('1252') # multiple aliases
[('1252', 'cp1252'), ('windows_1252', 'cp1252')]
>>> find('856') # no codepage 856 in aliases
[]
>>> find('koi8') # no koi8_u in aliases
[('cskoi8r', 'koi8_r')]
>>> 'x'.decode('cp856') # but cp856 is a valid codec
u'x'
>>> 'x'.decode('koi8_u') # but koi8_u is a valid codec
u'x'
>>>

另外，无论你用什么方法获取完整的编解码器列表，忽略那些与字符集的编码/解码无关，而是做其他转换的编解码器（比如 zlib、quopri 和 base64）可能是个好主意。

这就引出了一个问题：你为什么想要“尝试将字节编码成多种不同的编码”？如果我们知道这个，我们可能能更好地引导你。

首先，这个问题有点模糊。一个是将字节解码成 Unicode，另一个是将 Unicode 编码成字节。你想做哪个？

你到底想实现什么：你是在尝试确定使用哪个编解码器来解码一些传入的字节，并打算用所有可能的编解码器来尝试吗？[注意：latin1 可以解码任何东西] 还是你想通过尝试用所有可能的编解码器来确定一些 Unicode 文本的语言？[注意：utf8 可以编码任何东西]。
